For those who missed it:
It really seems A.E. Mourant’s paper reveals a belief that the Neanderthals did turn into the Basques.
We were interested in discovering where Rh-negative may have originated. We therefore drew up a “weather-map” of the genic distribution of Rhnegative. The resulting isogenic map led us to conclude that Rh-negative originated in Southwestern France. We conjectured the period at about 50,000 years, and the population probably a Neanderthaloid-like (!) one.
